  • $\begingroup$ The problem isn't the noise scale or amplitude, it's the range, and more precisely, when the waveform leaves it. The noise settings create the exact speed and feel of motion I want (Consider watching the attached video). Look at the negative spike on the right, it hits -0.05, then there is this 10-ish frame flat spot. The shape of the curve implies that the peak has been cut off. This seems to happen several times to various degrees (again, I would suggest watching the attached video). Also, I know it's hard to see, the the section is from frame 1 to 480 at 24fps, peak to trough is ~20 frames. $\endgroup$

  • $\begingroup$ @SomeSnowLeopard The amplitude is the range you're talking about. Remember, you are sampling your noise. You are not getting its shape between frames, only at the frames. And that can make the peaks appear "cut off." I have watched your video-- it looks like a noise modifier looks. I'm not sure what it is that you want instead. $\endgroup$

  • $\begingroup$ The range I am talking about is not the amplitude. I could set the strength to 100, and the negative spike on the right would still be clamped, just at -50 instead of -0.05. I have used noise modifiers a fair bit, and I have never seen one do what this does at 0:17. If you look at the waveform, it is obvious that something is wrong with that negative peak on the right. That looks as if a large portion of the wave has been clamped to the max range of the noise. For some reason, the noise function generated a waveform that left the prescribed -0.5 to 0.5 x strength range. $\endgroup$

  • $\begingroup$ @SomeSnowLeopard Looking at your file, and focusing on frames around 425, I see the clamping. (You might consider adding the info to your question if you want an opinion from somebody else-- but, that's probably unlikely anyways.) The issue is with the "phase" parameter, which creates an amplitude outside of the range for the strength. It shouldn't. The documentation (manual) for phase currently states that it changes the random seed for the noise, but it's clear that's not happening. (I believe it used to be the case, but apparently, not anymore.) I would consider this a reportable bug. $\endgroup$

  • $\begingroup$ @SomeSnowLeopard And, if you're just looking for a fix, don't change the phase so much. Yes, that will change your noise. But the phase changes are what are creating noise outside the range. If you report the bug, and you get some crap (maybe because of difficulty communicating the problem), please feel free to get my attention on the bug report and I'll chime in. $\endgroup$
